Europe heatwave latest: Eiffel Tower summit closed as continent faces record-breaking temperatures
Spain and Portugal logged their highest-ever June temperatures as authorities took urgent measures across Mediterranean nations.
Spain saw its hottest June since 1914, with Barcelona hitting 37.9C and Madrid forecast to reach 39°C while Portugal's Mora town peaked at 46.6C.
Italy banned outdoor work in some parts as red alerts were issued in 17 major cities. In Florence, power outages hit the city centre, and a worker near Bologna died in a suspected heat-related incident.
Turkey battled wildfires for a third day, forcing the evacuation of about 50,000 people.
The current high-pressure system set in late last week, bringing temperatures up to 10C higher than normal for this time in summer, with the system moving east across Europe from the Iberian peninsula.
Marine heatwave pushes up Mediterranean Sea temperature
Mediterranean Sea temperatures surged in June in a marine heatwave, with a Greek scientist warning some species are under threat in what has likely been a record period.
The EU's Copernicus Climate Change Service said Copernicus Marine Service data showed sea surface temperatures on 22 June were more than 5Cs above the seasonal average.
The most intense warming in what it called a "marine heatwave" was observed in the western Mediterranean basin, including the Balearic Sea, off Spain, and the Tyrrhenian Sea, off the west coast of Italy, it said.
"We have seen temperatures we were expecting in the middle of August being recorded in June and ... this is why it is considered a record year for temperatures in the Mediterranean Sea," Christos Spyrou, associate researcher at the Academy of Athens research centre for atmospheric physics, said.
He said that the average sea temperatures in June were 3-6 degrees higher than the average between 1982-2023, which was used as a reference period.
"We expected these sea temperatures in August," Spyrou said, adding specific temperatures were not yet available.
"Some species will not be able to reproduce or survive in these conditions, especially in increasing temperatures.'
Europe is the world's fastest-warming continent, heating up at twice the global average, according to Copernicus, making extreme heatwaves occur earlier in the year, and persist into later months.
Several Italian regions banned outdoor work during the hottest hours of the day on Tuesday, France shut scores of schools and Spain confirmed last month as its hottest June on record as a severe heatwave gripped Europe, triggering widespread health alerts.
A 69-year-old Greek resident who gave his name as Christos said he had noticed the warming waters off Athens.
'I have been coming here for 11 years, I believe the sea is a little warmer than other years. Every year it gets warmer, both in winter and in summer," he said

Schools and Eiffel Tower summit shut in France as red alert extended
France is on high alert as temperatures soar to 40–41C, with the red alert extended till today.
National weather agency Meteo-France placed several departments under the highest red alert.
The Eiffel Tower's summit remains closed until Thursday for 'everyone's comfort and safety'.
Visitors to the Eiffel Tower without tickets were told to postpone their visits.
The number of schools shut across the country has surged to nearly 1,900, up from just 200 on Monday, in a dramatic response to the intensifying heatwave.
A Paris-Milan rail service was disrupted because of a mudslide on the French side of the Alps, with full service not expected to be fully restored until mid-July, French rail operator SNCF said.

Barcelona logs hottest June in over a century
Barcelona logged its hottest June since 1914, with an average temperature of 26C.
Monday alone saw a searing 37.9C, breaking all previous records for the month.
Barcelona is usually spared the worst heat in Spain, thanks to its location between hills and the Mediterranean.

Europe is world's fastest warming continent
Europe is the world's fastest-warming continent, heating up at twice the global average, according to the EU's Copernicus Climate Change Service, with extreme heatwaves starting earlier in the year and persisting for longer.
"What is exceptional ... but not unprecedented is the time of year," said World Meteorological Organisation spokesperson Clare Nullis, adding that extreme heat episodes were seen now "which normally we would see later on in the summer."
Higher temperatures in the Mediterranean Sea tend to reinforce extreme temperatures over land areas, she said.

'Heatwaves are silent killers' - the dangers of extreme heat
Extreme heat kills up to 480,000 people annually around the world, according to insurance company Swiss Re, which notes this exceeds the combined toll from floods, earthquakes and hurricanes.
Dr Garyfallos Konstantinoudis, research fellow at the Grantham Institute, Imperial College London, said: "Heatwaves are silent killers.
"Unlike floods or storms, their impact can be invisible: people who die during extreme heat usually have pre-existing health conditions, and heat is rarely recorded as a contributing cause of death."

'Climate refuge' set up in southern Malaga by Red Cross
The Red Cross set up an air-conditioned "climate refuge" for residents in southern Malaga, said IFRC spokesperson Tommaso Della Longa.
Spanish Red Cross volunteers have been deployed to support the most vulnerable population groups – the very old and the very young, pregnant women, people working outdoors – and the National Society has launched a public-health information drive to provide advice on how to store medication safely and protect pets.
The Red Cross set up a 'climate refuge', air-conditioned down to the low twenties, to help residents 'cope with the heat in comfort and with company, avoiding the isolation and loneliness' that extreme heat can impose, as people are forced to stay indoors.

Barcelona marks hottest June in over a century
Barcelona recorded its hottest month of June since records started more than a century ago, Spain's national weather service said as Europe remained in the grip of the first major heatwave of the summer.
The Fabra Observatory, located on a hill overlooking the city, reported an average temperature of 26C, breaking records since 1914. The previous hottest average for June was 25.6C in 2003.
The same weather station said a single-day high of 37.9C for June was recorded on Monday.

Weatherwatch: Thirstier atmosphere brings more drought to northern England
After the driest spring for 132 years, two regions of England – Yorkshire and the north-west – have entered drought status. Some reservoirs have shrunk to half their volume and without substantial rain other regions could also enter drought status. But it's not just lack of rain that is the problem. A new study shows that a thirstier atmosphere is making droughts more severe and widespread around the globe. Researchers used climate data including temperatures, wind speeds, humidity and solar radiation to develop an 'atmospheric evaporative demand' index – essentially a measure of how thirsty the atmosphere is. From data going back to 1901, their findings, published in Nature, show that the atmosphere has become thirstier over time. This rising thirst has increased the area of land vulnerable to drought and is responsible for about 40% of the increase in drought severity over the last four decades. A thirstier atmosphere means that even in places where rainfall hasn't changed much, there are still worsening droughts. The researchers argue that atmospheric thirst needs to be factored in to our preparations for drought. Storing and conserving water won't be enough and we also need strategies to reduce evaporative loss, such as planting drought-resistant crops, improving soil health, restoring habitats to retain moisture, and more efficient irrigation systems.

Company's carbon credits raise questions about unproven ocean technology to fight global warming
The startup Gigablue announced with fanfare this year that it reached a historic milestone: selling 200,000 carbon credits to fund what it describes as a groundbreaking technology in the fight against climate change. Formed three years ago by a group of entrepreneurs in Israel, the company says it has designed particles that when released in the ocean will trap carbon at the bottom of the sea. By 'harnessing the power of nature,' Gigablue says, its work will do nothing less than save the planet. But outside scientists frustrated by the lack of information released by the company say serious questions remain about whether Gigablue's technology works as the company describes. Their questions showcase tensions in an industry built on little regulation and big promises — and a tantalizing chance to profit. Jimmy Pallas, an event organizer based in Italy, struck a deal with Gigablue last year. He said he trusts the company does what it has promised him — ensuring the transportation, meals, and electricity of a recent 1,000-person event will be offset by particles in the ocean. Gigablue's service is like 'an extra trash can' where Pallas can discard his unwanted emissions, he said. 'Same way I use my trash can — I don't follow where the truck that comes and picks up my trash brings it to,' he said. 'I'll take their word for it.' 'Hundreds of thousands of carbon credits' Gigablue has a grand vision for the future of carbon removal. It was originally named 'Gigaton' after the one billion metric tons of carbon dioxide most scientists say will be necessary to remove from the atmosphere each year to slow global warming. The company began trials in the South Pacific Ocean last year, and says it will work with country authorities to create a 'sequestration field' — a dedicated part of the ocean where 'pulses' of particles will be released on a seasonal basis. Gigablue says its solution is affordable, too — priced to attract investors. 'Every time we go to the ocean, we generate hundreds of thousands of carbon credits, and this is what we're going to do continuously over the upcoming years and towards the future, in greater and greater quantities,' co-founder Ori Shaashua said. Carbon credits, which have grown in popularity over the last decade, are tokens that symbolize the removal of one metric ton of carbon dioxide from the atmosphere. On paper, companies that buy credits achieve a smaller carbon footprint without needing to reduce their own emissions — for instance, by paying another vendor to plant trees or capture carbon dioxide from the air. Only a few countries have required local industries to purchase carbon credits. Most companies that buy them, including Microsoft and Google, do so voluntarily. The credits have helped fund a band of startups like Gigablue that are eager to tackle the climate crisis, but they are also unevenly regulated, scientifically complex, and have in some cases been linked to fraud. Gigablue's 200,000 credits are pledged to SkiesFifty, a newly formed company investing in greener practices for the aviation industry. It's the largest sale to date for a climate startup operating in the ocean, according to the tracking site making up more than half of all ocean-based carbon credits sold last year. And it could beckon a rapid acceleration of the company's work. Gigablue hopes to reach a goal this year of capturing 10 metric tons of carbon dioxide for each ton of particles it deploys, Shaashua said. At that rate, Gigablue would disperse at least 20,000 tons of particles in the ocean. Gigablue wouldn't reveal what it earned in the sale, and SkiesFifty's team declined to be interviewed for this story. Most credits are sold for a few hundred dollars each — but a chart on Gigablue's website suggests its prices are lower than almost any other form of carbon capture on the market. A mission to save the world The startup is the brainchild of four entrepreneurs hailing from the tech industry. According to their LinkedIn profiles, Gigablue's CEO previously worked for an online grocery startup, while its COO was vice president of SeeTree, a company that raised $60 million to provide farmers with information on their trees. Shaashua, who often serves as the face of Gigablue, said he specializes in using artificial intelligence to pursue positive outcomes in the world. He co-founded a data mining company that tracked exposure risks during the COVID-19 pandemic, and led an auto startup that brokered data on car mileage and traffic patterns. 'Three years ago, I decided to take the same formula, so to say, to climate,' Shaashua said. Under his guidance, he said, Gigablue created an AI-driven 'digital twin' of the ocean based on dozens of metrics to determine where to release the particles. Chief technology officer Sapir Markus-Alford earned a bachelor's degree in earth and environmental sciences from Israel's Ben-Gurion University in 2021, shortly before founding Gigablue. Markus-Alford said she began her studies and eventual path to Gigablue after seeing bleached coral reefs and other impacts of warming waters on a series of diving trips around the world. 'I understood that the best thing we could do for the ocean is to be able to remove CO2,' Markus-Alford said. A spokesperson for Gigablue did not answer whether the other co-founders have graduate degrees in oceanography or environmental science, but said the company's broader team holds a total of 46 Ph.D.s with expertise in biology, chemistry, oceanography, and environmental science. Markus-Alford said that figure includes outside experts and academics and 'everyone that supports us.' The company's staffing has expanded from Israel to hubs in New York and New Zealand, Shaashua said. In social media posts advertising open jobs, Gigablue employees encouraged applicants to 'Join Our Mission to Save the World!' Trapping carbon at the bottom of the ocean The particles Gigablue has patented are meant to capture carbon in the ocean by floating for a number of days and growing algae, before sinking rapidly to the ocean floor. 'We are an elevator for carbon,' Shaashua said. 'We are exporting the carbon from the top to the bottom.' Algae — sometimes referred to as phytoplankton — has long been attractive to climate scientists because it absorbs carbon dioxide from the surrounding water as it grows. If the algae sinks to the deep sea or ocean floor, Gigablue expects the carbon to be trapped there for hundreds to thousands of years. The ultimate goal is to lower carbon dioxide levels so drastically that the ocean rebalances with the atmosphere by soaking up more CO2 from the air. It's a feat that would help slow climate change, but one that is still under active study by climate scientists. Gigablue's founders have said the company's work is inspired by nature and 'very, very environmentally safe.' The company's particles and sinking methods simply recreate what nature has been doing 'since forever,' Shaashua said. Gigablue ran its first trial sinking particles in the Mediterranean in March last year. Later, on two voyages to the South Pacific, the company released 60 cubic meters — about two shipping containers — of particles off the coast of New Zealand. Materials kept a mystery While Gigablue has made several commercial deals, it has not yet revealed what its particles are made of. Partly this is because the company says it will build different particles tailored to different seasons and areas of the ocean. 'It's proprietary,' Markus-Alford said. Documents provide a window into the possible ingredients. According to information on the permit, Gigablue's first New Zealand trial last year involved releasing particles of pure vermiculite, a porous clay often used in potting soil. In the second New Zealand trial, the company released particles made of vermiculite, ground rock, a plant-based wax, as well as manganese and iron. A patent published last year hints the particles could also be made of scores of other materials, including cotton, rice husks or jute, as well as synthetic ingredients like polyester fibers or lint. The particles contain a range of possible binding agents, and up to 18 different chemicals and metals, from iron to nickel to vanadium. Without specifying future designs, Markus-Alford said Gigablue's particles meet certain requirements: 'All the materials we use are materials that are natural, nontoxic, nonhazardous, and can be found in the ocean,' she said. She wouldn't comment on the possible use of cotton or rice, but said the particles won't include any kind of plastic. When asked about vermiculite, which is typically mined on land and heated to expand, Markus-Alford said rivers and erosion transport most materials including vermiculite to the ocean. 'Almost everything, basically, that exists on land can be found in the ocean,' she said. The company said it had commissioned an environmental institute to verify that the particles are safe for thousands of organisms, including mussels and oysters. Any materials in future particles, Gigablue said, will be approved by local authorities. Shaashua has said the particles are so benign that they have zero impact on the ocean. 'We are not changing the water chemistry or the water biology,' Shaashua said. Ken Buesseler, a senior scientist with the Woods Hole Oceanographic Institution who has spent decades studying the biological carbon cycle of the ocean, says that while he's intrigued by Gigablue's proposal, the idea that the particles don't alter the ocean is 'almost inconceivable.' 'There has to be a relationship between what they're putting in the ocean and the carbon dioxide that's dissolved in seawater for this to, quote, work,' Buesseler said. Buesseler co-leads a nonprofit group of scientists hoping to tap the power of algae in the ocean to capture carbon. The group organizes regular forums on the subject, and Gigablue presented in April. 'I left with more questions than answers,' Buesseler said. Scientists raise questions Several scientists not affiliated with Gigablue interviewed by The Associated Press said they were interested in how a company with so little public information about its technology could secure a deal for 200,000 carbon credits. The success of the company's method, they said, will depend on how much algae grows on the particles, and the amount that sinks to the deep ocean. So far, Gigablue has not released any studies demonstrating those rates. Thomas Kiørboe, a professor of ocean ecology at the Technical University of Denmark, and Philip Boyd, an oceanographer at the University of Tasmania who studies the role of algae in the Earth's carbon cycle, said they were doubtful algae would get enough sunlight to grow inside the particles. It's more likely the particles would attract hungry bacteria, Kiørboe said. 'Typical phytoplankton do not grow on surfaces, and they do not colonize particles,' Kiørboe said. 'To most phytoplankton ecologists, this would just be, I think, absurd.' The rates at which Gigablue says its particles sink — up to a hundred meters (yards) per hour — might shear off algae from the particles in the quick descent, Boyd said. It's likely that some particles would also be eaten by fish — limiting the carbon capture, and raising the question of how the particles could impact marine life. Boyd is eager to see field results showing algae growth, and wants to see proof that Gigablue's particles cause the ocean to absorb more CO2 from the air. 'These are incredibly challenging issues that I don't think, certainly for the biological part, I don't think anyone on the planet has got solutions for them,' he said. James Kerry, a senior marine and climate scientist for the conservation group OceanCare and senior research fellow at Australia's James Cook University, has closely followed Gigablue's work. 'What we've got is a situation of a company, a startup, upfront selling large quantities of credits for a technology that is unproven,' he said. In a statement, Gigablue said that bacteria does consume the particles but the effect is minimal, and its measurements will account for any loss of algae or particles as they sink. The company noted that a major science institute in New Zealand has given Gigablue its stamp of approval. Gigablue hired the National Institute of Water and Atmospheric Research, a government-owned company, to review several drafts of its methodology. In a recent letter posted to Gigablue's website, the institute's chief ocean scientist said his staff had confidence the company's work is 'scientifically sound' and the proposed measurements for carbon sequestration were robust. Whether Gigablue's methods are deemed successful, for now, will be determined not by regulators — but by another private company. A new market is one of several companies known as registries that serve the carbon credit market. Amid the lack of regulation and the potential for climate startups to overstate their impact, registries aim to verify how much carbon was really removed. The Finnish has verified more than a million carbon credits since its founding seven years ago. But most of those credits originated in land-based climate projects. Only recently has it aimed to set standards for the ocean. In part, that's because marine carbon credits are some of the newest to be traded. Dozens of ocean startups have entered the industry, with credit sales catapulting from 2,000 in 2021 to more than 340,000, including Gigablue's deal, last year. But the ocean remains a hostile and expensive place in which to operate a business or monitor research. Some ocean startups have sold credits only to fold before they could complete their work. Running Tide, a Maine-based startup aimed at removing carbon from the atmosphere by sinking wood chips and seaweed, abruptly shuttered last year despite the backing of $50 million from investors, leaving sales of about 7,000 carbon credits unfulfilled. In June, published a draft methodology that will be used to verify Gigablue's work, which it designed in consultation with Gigablue. Once finalized, Gigablue will pay the registry for each metric ton of carbon dioxide that it claims to remove. Marianne Tikkanen, head of standards at said that although this methodology was designed with Gigablue, her team expects other startups to adopt the same approach. 'We hope that there will be many who can do it and that it stimulates the market,' she said. The road ahead It remains to be seen whether New Zealand officials will grant permission for the expanded 'sequestration field' that Gigablue has proposed creating, or if the company will look to other countries. New Zealand's environmental authority has so far treated Gigablue's work as research — a designation that requires no formal review process or consultations with the public. The agency said in a statement that it could not comment on how it would handle a future commercial application from Gigablue. But like many climate startups, Gigablue was involved in selling carbon credits during its research expeditions — not only inking a major deal, but smaller agreements, too. Pallas, the Italian businessman, said he ordered 22 carbon credits from Gigablue last year to offset the emissions associated with his event in November. He said Gigablue gave them to him for free — but says he will pay for more in the future. Pallas sought out carbon credits because he sees the signs of climate change all around him, he says, and expects more requirements in Italy for businesses to decarbonize in coming years. He chose Gigablue because they are one of the largest suppliers: 'They've got quantity,' he said. How authorities view Gigablue's growing commercial activity could matter in the context of an international treaty that has banned certain climate operations in the ocean. More than a decade ago, dozens of countries including New Zealand agreed they should not allow any commercial climate endeavor that involves releasing iron in the ocean, a technique known as 'iron fertilization.' Only research, they said, with no prospect of economic gain should be allowed. Iron is considered a key ingredient for spurring algae growth and was embedded in the particles that Gigablue dispersed in October in the Pacific Ocean. Several scientific papers have raised concerns that spurring iron-fueled algae blooms on a large scale would deplete important nutrients in the ocean and harm fisheries. The startup denies any link to iron dumping on the basis that its particles don't release iron directly into the water and don't create an uncontrolled algae bloom. 'We are not fertilizing the ocean,' Markus-Alford said. 'In fact, we looked at iron fertilization as an inspiration of something to avoid,' Shaashua said. But the draft methodology that will use to verify Gigablue's work notes many of the same concerns that have been raised about iron fertilization, including disruptions to the marine food web. Other scientists who spoke with AP see a clear link between Gigablue's work and the controversial practice. 'If they're using iron to stimulate phytoplankton growth,' said Kerry, the OceanCare scientist, 'then it is iron fertilization.' For now, scientific concerns don't seem to have troubled Gigablue's buyers. The company has already planned its next research expedition in New Zealand and hopes to release more particles this fall. 'They mean well, and so do I,' said Pallas, of his support for Gigablue. 'Sooner or later, I'll catch a plane, go to New Zealand, and grab a boat to see what they've done.' — This story was supported by funding from the Walton Family Foundation.

UK weather: Forecast for July revealed - after England's warmest June on record
We've just had the warmest June on record for England and the second-warmest June for the UK, but will July be similar? It was certainly a hot and humid start across the South East of England, with 34.7C (94.5F) seen at St James's Park in London yesterday. That's the UK's highest temperature of the year so far but a long way off the highest recorded in July, which is the national record of 40.3C (104.5F) seen at Coningsby on 19 July 2022. 1:58 The rest of this week will bring fresher and cooler conditions overall, with daytime temperatures widely below average on Sunday and Monday. The weather will turn more unsettled too - especially over the weekend - with spells of rain for most. It'll also be windy at times. From the middle of next week, it looks like pressure will build from the South West, settling things down again. Temperatures are likely to climb as well, potentially becoming very warm or hot again towards the middle of the month depending on the exact position of high pressure. 1:40 Looking further ahead, there is a lot of uncertainty for the last two weeks of July, with computer models showing a range of options. Farmers and gardeners will be hoping for some decent rain after the second-driest spring on record for England and the sixth driest for the UK. Some parts of northern England are already in drought conditions, other areas may well follow. Recent Julys have delivered a range of weather. July 2022 saw extreme heat, with the UK recording its highest-ever temperature. July 2023 brought notable rain, with some areas seeing more than twice the average. Last year, temperatures ended up being below average after the coldest start to July since 2004.
